[Reversible dilated cardiomyopathy induced by ventricular asynchrony].
The authors present the case of a patient who developed left bundle branch block with asynchrony of left ventricular contraction and, secondarily, a dilated hypokinetic cardiomyopathy. There were no signs of an ischaemic, toxic or inflammatory cause for the cardiomyopathy whereas cardiac resynchronisation by biventricular stimulation rapidly restored a normal left ventricular ejection fraction. This suggests that asynchrony of left ventricular contraction is not necessarily the consequence of a dilated hypokinetic cardiomyopathy but it may also be considered as a possible cause.
